IMPROVEBNT IN ROLLER-WHEELS FOR PLUGES.

To ALLYWHOM Ir MAY coNcERN:

Be it known that I, LEMAN B. PIT'JHER, of thc'town of Salina, in the county of Onondaga, and State of New York, have invented a new and improved Roller-Wheel for Ploughs and'Cultivators, and the manner of mounting the same; and l do hereby declaro that the' following is a full, clear, anfl exact description of the construction of the same, and the mode of operation thereof when complete and ready for use, referencevbeing had to the anneired drawings, forming a. part of this specification, in which v Figure 1 represents a perspective view of the roller when applied to a plough, and

Figure 2 represents a like view when applied to a cultivator.

Figure 3 represents one ofthe segment-frames used en the roller, and

Figure el represents a cross-sectional view through the centre of the axle of the roller, showing also the situation of the protecting-cups and theattachmentof the segment-frames.

Figure 5 represents a perspective view of'the thimble-shaped cup.

The letters used represent corresponding parts wherever they occur. Y

I am aware that segments have been applied to rollers while used for cultivators and frames or braces to rollersiused for ploughs, but not so constructed in 'either instance as to be'service'dble alike for both plo'ghs and cultivators.A My segment-.frame can be used upon a roller while for a plough as Well as cultivator. In the v rollers in common use, the axles land bearings wear out very rapidly, because there'is no suiicient protection against the dust and dirt.' To obviate that diiiculty, I place upon the s haft or axle a-.thimble-shaped cup, enclosing the end of' the shaft, (as shown in the drawings,) which I have invented, und which, I claim, has a more ektn= sive application than lits use upon rollers, which are for ploughs `and cultivators. It vmay be used to cover like bearings in harvesters, drills, threshing machines, and other machines or implements, where it-is desirable to keep out the dust and dirt which usually increase the wear and, friction. 'When the roller revolves on its own shaft a ange of suitable proportions may beV made to project from thshub ofthe roller-wheel, so as 'to surround the shaft and protect the bearing from dirt and dust in` combination with the cup. All the parts ofthe roller-wheel may be made of iron or other suitable materials. The size and proportions of thc various parte inthe combi nation of this roller-wheel may be varied as circumstances require, and otherwise made tot the roller and beams:

I construct the roller-wheel itself with a rim or ange, f, and with spokes s's 8.8, in thecommonl size and form for ploughs land cultivators, which wouldbe ordinarily about six to eight inches in diameter, and with]v the flangef about two'inches wide. The shafts or axles a a form a, part'of the roller(ulthough they may be in u. separate piece or pieces properly fastened,) and at 'the inner end `such'shafts are protected somewhat by the pr0 jecting edges E E. It is better to make the shafts with slight shoulders, c c, sothatbctween l.that and similar shoulders on the inside of the cups C C there may be space fora ring or washer of leather or `other vmaterialfor packing in the usual manner when desired, and thus still more eiectuallydieep out the dust and dirt. I make the thimble-shaped cups C C about three inches long, 'one end closed'and the other open, so that they will easily t upon the shafts a tt with shoulders'd d on the inside, at 'a suitable distance, say half an inch from the correspondingshoulders c c onthe shafts a a, for the purpose of using a'packing, if that is desired, as above stated. These shoulders are not absolutely essential, however, upon either the shafts or cups, and the;r may 'bemade so that the shafts will easily fit the inside of the cups the wholelength ofthem, and operate like' it i common frictioncone. I consider it better, too, to make the cups C C a little flaring toward their open end,.s0 that they will snugly t under the projecting edges E E, and hinder the ingress of dust and dirt, and dis= Charge 1what may pass into the cups. I make the cups C C with keys b b onthe sides, toiit into key-seatsou the inside of the coupling-holes y g of the segment-frames B B, or they may be held in `any other common man ner. Thus the cups hold -the ends ofthe shafts, and they are heldin the coupling-holes ofthe segment-frames. I make the segmentfframes B B with the arms v v, between which are the short segments t and the armsv c u are so made that, from a point near the under side of the lower segments L'L to'thc top .of the arms, they run parallel to'each other, and the short segments L are also made to r'un parallel to each other. From the under side of the lower segments L L'the arms curve gradually, and finally mcetitogether in thc head for coupling-holes g g, which are made with a bearing on the inside broad enough to hold them steady, and so as to it over and upon the cups O C, and snugly against the shoulders z'z' on the outside of the cups. The couplingholes g g are also furnished with the key-seats t t to receive the keys I1 6 on the cups and hold them to their place. .By moving the keys `from seat to seat, a di'ereut bearing is produced, and the use of the cup prolonged. -A different been i ing is also e`ccted when the roller is changed from* one of said implements to the other.

When the segment-frame is applied to cultivatoi's the central pivot will be in the upper short segments lL 7L,

at the hole p, and both the arms and segments will be furnished with baiting-holes about three-eighths oi' :,Ln

inch in diameter and about three-fourths of an inch opart. When applied to ploughs, the arms v v are made to' 'rise or fall together. s

The segment-frames ordinarily stand about two n-nd three-quarter inches apart, to meet the common size oi" Wood beams in ploughs or cultivators, but when iron is used instead of-wood. the segment-frame will be bent above the wheel to fit the same.

What I claim as my irivention, and desire to secure by Letters Patent, is-

1. The segment-frames B B and th'e cups C C, whenpplied to n. roller-wheel for inloughs and cultvators, each separately and in combination with each other, substantially as and for the purposes described.

2. I also claim the same parts in combination with' the r0llerWheel A, operated upon the shafts a a, substantially as and for the purposes described. y
